Sounds like your BIOS has been corrupted, or someone has changed your BIOS settings. Flash you BIOS to it's defaults and reboot. I don't know enough about your system to explain how (systems are all different). Generally there is a jumper near the CMOS battery that needs to be removed, then the power turned on and off, then the jumper replaced.

Everytime you enter Cmos Setup you the time is the same (date and time) ?

If so maybe your system has a discharged battery. It happens in old computers. If it is your situation then you need to replace the battery.

Once the battery is replaced you need to configure Setup. There are several things, but the main things are:

-Set the date and time
-Choose the appropriate floppy type (1,44 is the usual)
-Look for an item described as HDD Detect and press Enter on it to detect the correct HD.
-Save the changes and try to boot

"Fixed disk" means your harddrive, from the sound of it your harddrive is dead, or as suggested above the BIOS is not recognizing it properly. What kind of computer is this? The error wording sounds like an IBM system...in either case, see if you can find the Setup location where it defines IDE Devices, ATAPI devices, Fixed Disk drives, Storage devices, etc (exact wording depends on the system). If its showing Fixed Disk 0 "Not Installed" then your drive is shot. Hopefully your warranty is still valid.

Provide some system details please, specifically the make/model of the PC (if its an IBM, I need the entire part number, i.e. 6579-78A which should be on the front of the system on a black label).
